This invention relates to improvements in atomizing nozzles for atomizmg liquids of all kinds, such as water, blood, lyes, acids, and the like, the object of the invention bein .5. to effect improvements in the construction the mouth piece of the nozzle and'to provide the same with an insert piece, which insert piece is made of soapstone or other brittle and acid resisting material and is se- 1 cured inthe mouth piece of the nozzle by bending in or spinning the outer edge portion of the wall of the mouth piece around and partially over the outer end of the insert, so that the latter is firmly secured in the v mouth piece and obviates the use of screw threads for such securing purpose.

Another ob'ect of the invention is to provide a metal s eathing element for the insert, which sheathing element is provided with perforations and serves for guiding'a movable atomizin insert or for attaching the guiding man rel of a movable insert for the nozzle. I

With the above and other objects in view, the invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

By way of example, the object of the invention is shown in the attacheddrawings in some forms of construction.

In the drawings,

Figure 1 is a longitudinal section through a nozzle with a freely movable insert.

Figure 2 is a longitudinal s ction through a nozzle with a guided insert.

Figure 3 is a longitudinal section through a nozzle with a ball insert.

Figure 4 is a top plan view of the ball insert of Figure 3.

Figure 5 is a lateral view of the ball insert of Figure 3. I v

In all of the embodiments illustrated herein the nozzle comprises a casing G which is provided at the bottom with 'a screw portion A and a feeding passage C for the liquid to be atomized. The mouth M of the nozzle is provided 'with an insert S. Within the nozzle itself is located a movable atomizer E provided advisably with curved actuating passages T so arranged that these passages terminate in the upper surface of the insert tangential to the axle of the nozzle in a circumferential feeding groove U which is located to the rear of the mouth M.

The inserted parts S may consist of soap- 6!! stone, steatite, ceramic material or any other tough artificial mass being resistant against chemical influences. These materials are not only chea er than metals, but are also almost acid-proo and in spite of bein easily do worked they are extremely hard an capable of resistance. However as they are less suited for threads, the casing (it as well as the thread union A aremade of metal.

In Figure 1 the nozzle insert S is surround- 05 ed with channel perforations B. This nozzle insert S together with this iece Z; is positioned in a casing or housing by bendlng over the tongues or projections L of the housing, which projections are made of bend- 7o able material. This bending is effected by rollers. Before applying the rollers it is obvious that the atomizer 1nsert E must have been positioned within the part S. This movable lnsert Eis provided with two ends which are beveled and in which the feedin passages T have been out. According to Fig.1? only a packing ring D rovided with e perforations B is provi ed for the nozzle, whilst the fastening of S is effected by solely flanging the rolled lap L of the casing G. The atomizer insert E which is conical and which is provided with a point E is guided by means of a stem or spindle P in the gasket rinlg D. n Fig. 3 a nozzle is shown with a ball E sliding on a pin 0 and working automatically. The fastening and tightening of the inserted part S is effected by means of tongues L of the casing G and a cap-shaped insertion B. The atomizer insert E comprises a ball which has been positioned on a stem 0. The stem 0 is secured to the insert H. Theupper part of the socket in the ball for attachment to the stem has been cut out to form an annular liquid passage U. In this passage U the cuiiyed actauting passage T opens tangentia y.

The operation of the nozzles illustrated herein is about as follows: 10o

When the liquid is admitted to the nozzle, the liquid flowing through the channel of the passage C forces the insert E upward so that the conical surface of the inserts of Figures 1 and 2 on the upper part of the ball of Figure 3 engages the correspondingly conical inner surfaceoftheinserts. The liquid then leaves the mouth of the nozzle solely by flowing through the actuating passages T and owing to the tangential terminal portion located in a front of the mouth of the nozzle the liquid is imparted a very intensive whirling movement and is discharged from the mouth in the form of a conical jet which rotates continuously and which operates over a largesurface. The jet is interru ted on numerous points uniformly in suc manner that the entire discharge comprises merely a spray of water. By friction of the water on the nozzle and in the air and owing to the condenser eflfect of the atomizing Water the little drops of water are charged electrically and this electric charge is facilitated by the mineral insert made of soapstone. The higher electric charge of the spray of water has a favorable influence on the catalytic effect of the surface of the spray and serves for facilitating or accelerating the reaction. If in nozzles of this kind the admisson of the liquid is an interrupted one, if the liquid is alternately shut off and turned on or if the pressure intermittently is varied, the atomizer nozzles are intermittently spaced from the mouth inserts and hence the actuating channels are cleaned directly up to the very month thereof by the liquid flowing therethrough, which liqu1d washes away any deposits which might be formed.

I claim:

1. An atomizer nozzle for liquids having a mouth open at the outer end, a fixed insert of material which is brittle and neutral against chemical reactions, arranged in said mouth and also having a movable atomizer insert provided with driving channels, the wall of the'mouth being directly extended inwardly partly over and around the outer end of the insert and securing the latter in place.

2. An atomizer nozzle, as set forth in claim 1, including a perforated sheath piece inserted between the inlet of the nozzle and the insert and having a central opening for guiding a stem of a shiftable atomizer insert.

3. An atomizer nozzle as set forth in claim 1, including a stem with which the sheath piece is provided and a shiftable ball on said stem and movable between the sheath piece 1 and the insert.
